Question

According to the theory the mass’s change in momentum and the impulse experienced by the mass should be the same. What is the % difference between the magnitude of the Δp and Iarea for each of the separate runs. Does this data seem to support the theory?

Answer 1

from the given data of information

	rubber	thick spring	thin spring
mvi	0.5007*0.754 = 0.378	0.5007*0.769= 0.385	0.5007*0.751= 0.376
mvf	-0.337	-0.299	-0.311
$\Delta t$	1.346-1.328= 0.018	0.054	0.11
area	0.330	0.711	0.776
$\Delta p = mv_f - mv_i$	-0.715	-0.684	-0.687 N
favg	26.577 N	12.686	6.808N
dp = favg* $\Delta t$	26.577*0.018= 0.478	12.686*0.054= 0.685	6.808*0.11= 0.749 N

rubber ={ |-0.714| |-530|}/|-0.715| *100

            =25.90%

thick   = |{0.684-0.711}/0.684|*100

            = 3.95%

thin = |{0.687-0.776}/0.687|*100

       = 12.35%
